Using Probability in Big Data! #computerscience #algorithms #coding

This is ONLY useful for hobby work and super niche low budget situations.

As a professional developer I can personally say you will NEVER need to do this. All major services are so memory overloaded that you could store every single user, even doubling up on unique ones every time they visit, and still never run out of storage for YEARS. The more traffic usually means more money usually means more storage space.

If you can't store a unique record per user you've got bigger problems

[trey]

This won’t help you keep track of the exact unique visitor count though, since duplicates could happen

[wilkesreid]

Eventually you only store one record, and that means 1 million unique visitors

Another idea is to have cookies to know if is the first time the user joined. Then, if is the first time, sum the global integral, so fills the memory slower.

I really like this idea. For example this could be great when doing work on combinatorics or graph pathings. These operations can quickly become O(n^x) where x is very large. You inspired me with this simple idea thanks.

no wonder why I visited a website and leave for 2 months, when i came back, I have to sign in again

[promixinc.]

Hey. Can you do a quick video of python threading. If It would be wonderful. Thank you

[HemalPandya-blom]

This is the one way to create new problems

[jaswdrTheDev]

The problem is that the error increases as you decrease the probability rate

[jadenpark]

great video! could you make a video of hyper log-log or theta-sketch too?

[somerandomdude]

_Could_ just have a number that goes up by 1 every time someone goes to the website

[edistefi]

Dont we just use a 64 bit variable which we increment everytime a user joins?

[APerson-]

use 4 bytes to save ip
save all the data.
i'm sorry but if you don't have enough storage to record this then you got an issue.

[montagetm]

What if a user you deleted comes back to the website, wouldnt they get logged again

[lorenzweb]

Just increment a single row in a postgres database for each new visitor

[Codeccino]

Great explanation 🌹can I know what applications you use to create these fancy graphics and animations?

[teainnit]

That's assuming every person that enters your site has an equal likelihood of being either new or old, which is probobly not true at all.

[mnlog]

how are u gonna make sure if a visitor is a new one if u dont save his data?

[Nameless.]

Maybe I'm missing the point but if your trying to keep track of how many unique users visit your website can't you just store a number that increments for every new user
